I'm designing a new logo for a client and I would like a rectangular form on the background. There is a C-formed shape in the rectangle which should be clipped in the final version. (so if used on black background for example, there's only the regular form on the background with the C in it, but not the shape of the C outside the rectangle on the left and right of the rectangle).

Clipping could be an option but it gives me those fine strokes...

How to solve this?

Thanks!

The first image is the ideal result (but not clipped so with shapes of the C outside the box on a coloured background). The 2nd is the result when clipped. Note the small lines where the C-shape touches the borders of the rectangle on the left, right and bottom of the rectangle.

I must say it is already more how I would like it, but now the thing is: the C-shape has to remain white when I place the logo on for instance a red background. But only the C-shape within the blue rectangle, so the parts of the shape that come over the borders of the blue rectangle, should be gone (like the effect of a clipping mask actually... )

2) Delete unwanted parts (of the C), you may Ungroup or use Direct selection Tool?

You can still change the rest of the C to transparent by deleting those parts too, or by hiding them (in the Layers palette, or setting them them to nostroke/nofill), if your client changes mind again. In the latter case, you can (re)show/fill them if your client changes mind again again.
